Two-rotor Compression Tester Model ReCT-TRT User Manual
Using the ReCT-TRT, Rotary-engine Compression Tester System
The ReCT-TRT, rotary-engine compression tester is used to obtain accurate engine compression measurements in a rotary (i.e., Wankel) engine. Model ReCT-TRT can be used to conduct compression tests on two rotors simultaneously. The System combines the output from high-precision, AST pressure transducer(s) with the data conversion function of a DATAQ analog-to-digital device to acquire and record accurate compression readings for each face of each rotor in a rotary engine. This system also allows the calculation of engine cranking RPM during the test that can be used for data normalization as necessary.
Model ReCT-TRT consists of a Processing Unit (items 1-4) and two Acquisition Units (items 5-7). The Processing Unit includes an enclosure that houses the analog-to-digital converter, along with power, USB and DIN data connections. Included with the Processing Unit enclosure is a power cable, USB cable and the WinDaq Resource CD. The Acquisition Unit includes a high-precision, pressure transducer with attached 30-inch cable, a quick coupler and a spark plug hole adapter with swivel air plug. This user manual details the procedures for configuring and using the software for simultaneous, 2-rotor testing.
